I TYING MECHANISM FOR BALING PRESSES. l

. Application ined July as, 1920. serial No. 398,419.

To all whom t may concern:

Be it knownthat 1, ALBERT Gnlnvns, a citizen of the United States, residing at Springield, in the county of Clark and State of Ohio, haveinvented certain newv and useful Improvements in rlying Mechanism for Baling Presses, of which the following is a full, clear, and exact specifica'- tion.

My invention relates to automatic tying devices and more particularly to mechanism for binding compressed bales oi' hay or like material with wire and tying or twisting the wire or wires at the completion of each bale without interruption of the baling process.

The objects of my invention are to pro-` vide a bale tying device for baling presses of -the plunger type that will ope-rate smoothly and with minimum use of power and that will not interfere Withihe action. of the baling mechanism, that can be thrown into operation at any time and that will be actuated only on retraction of the plunger. Also, to provide -against binding or entanglement of the wire in the twisting` mechanism and against protrusion of the joined ends of wire from the finished bale.

This has. been accomplished by providing carriages slidably mounted on the baler fra-me including a-trip controlleddevice by which one of the carriages is made to reciprocate once with the plunger and is then automatically disconnected therefrom, this carriage carrying means for actuating wire carrying arms which carry the bindin wires across the compression chamber an into the twisting mechanism, the other carriage then serving to ydrive the twisting mechanisms. Said mechanisms including means for positively ejecting the intertwisted ends ofl the wires' and withdrawing them into the path of the plunger by which th- .y *are pressed into the bale;

With the above main and other minor objects inview, my invention'consists of ,the organization, combinations of elements, parts or their e uivalents, hereafter described and particular ydefined in the claims.

The parts comprising my invention are shown in connection. with a baling press having the usual baling chamber A and vpl ung-er B reciprocated by pitman C from a source of power not shown. At opposite points on the top and bottom of the chamber A trunnions are provided on which the horizontal arms ol a swinging bail 3l are jou rnaled. This bail is preferal'ily torined ol' a. member 3l bent at right angles and l'ornr ing the vert-ical and upper horizontal arm of the bail, and an angularly bent member 3lb joined to the lower end of member tt and forming the lower horizontal arm ol' the bail. The vertical arm or portion of the bail has fixed thereto at properly spaced points, the ends of two wire carrying arms or fneedles 32 which are preferably adjustable vertically on the bail and locked against: turning on their bearings by a spline, as at v32 (Fig. The arms 3Q are curved on an are approximately about the trunnions :to and'swinging of the bail carries the arms through o )enings in 'the sides oll the. baling and horizontally across it. the ends of the arms extending some distance beyond the opposite Wall of the chamber when at their limit of movement. 'lhe arms 32 are preferably formed -with a vertical and va horizontal flange andwire guides 82" are rovided at'the base Aand intermediate the ength of each arm whiletheir ends are formed with an eye :32c (Figs. 174-16) opening intoabifurcated tip 32 in which there is mounted a" wire receiving pulley 32". Inwardly of this pulley, the wings or sidesI ol the brlureated tip are turned in as at i (Fig. l5) and theivertical flange olt the. arm 32 is displaced-toward the axis lol.E the. arm to form a tie engaging pocket 32K. .Roller brackets 33 (Figs. l and 2) are provided to support the tie wires.

As means for swinging the bail :l1 and itsl wire carrying arms, I employ the plunger B which is operatively connected to the hail 3l in the following manner:

Approximately at the bend in the lower member 3F of the bail Ill there is pivotally connected thereto at 34 one end ol a pitzinan 35 which is bent to extend outwardly and upwardly, as seen in Figs'. l and 2. to bring its other end up to that side of the baling chamber on which the bail and wire arms l2 are carried, where it is pivotally connected 'as at 36 to a carriage 37 slidably mounted between upper and lower guides 38 on the .side of the press. On this carriage there is mounted on the horizontal pivot 39 a rearwardly extended coupling arm 40 which has its end formed into a hook 40 while its pivot end has a forwardly'projecting lug or heel 40h. Normally, the arm lt0 is locked in elevated or inoperative. position by a latch il pivoted on the carriage and l'ornied with a 'ltirwardly extended hooked bill 41"* and a downwardly extended arm 'lsl".

A compression spring ll engages a ledge, on the hitch and a lug on the carriage and norlnally presses the arm "il" ot the latch towards the heel 10", and the bill 4l toward a lug` 4t2 on the press traine. liroted inter mediate its ends onthe. press l'ranie, just below the lug 'l2 there is a latch releasing lever /ll which has one end positioned to engage the upper part ol latch 4l and its other end connected to a link l1. which in turn is con nected to the cranked end Alo oll a hand op4 cratcd lever or bail flt. i\ spring #1T piaci-o between a. lug lh on the press and hitch le ver fi' normally holds it in contact with one edge of the lug. When the. arm -ltl is inop erativc, the lower end ll" of latch l1 is en` gaged with the top ol' heel `itl" and the hooked bill fl-l engages lug l1! to retain the carriage 37 in its forward position. l `or the purpose olf locking ythe carriage T at its rearward position, there is provided a series ol,intercngaging pawls, at), 5t) and 5l. llear pawl ttl overlics pawl 5t) and is l'ornicd with a` hooked bill 'll" adapted to engage a lug` 52 on the press frame and with a cani tail 49". lawl 5() is mounted on the saine pivot as pawl it) and has a. guiding slot engaging a stud on the carriage. lt also has a tail ."o with a pin 50" projecting t'roni its tace in position. to engage tho lower edge ol' cain tail and its lower edge. is ot' arcuate torni interrupted by a step l'or co-operation willi pawl 5l, ending in a vertical edge titl" positioned to engage lugrl. lawl :"l has two arins approximately at right angles and is pivotcd to thc. carriage. with one arui in substantially vertical and the other in hori zontal position. 'l`he upper rear edge oll the vertical ariu has a tooth bl tor coopcrzr tion with step 50 and its lower torward edge is adapted lo engage a. stop lug .32% on the press l'ranic. ltsl horizontal ariu is slightly bowed upwardly and itsI upper edge l'ornis a cani tracliavhilc its lower edge is engaged by a spi'ing :il mounted on a lugon the carriage which normally presses the horizontal arm ol' pawl bl upwardly and toward pawl 5t).

l"or the purpose of engaging arm `ttl to reciprm-atc the carriage 25T and related mechanism. a pair ot' bars .on is secured (o the side ol' the, plunger li and these converge rearwardly and are joined to a bracket .no having a laterally extending stub sha l't. .7T on the inner portion of which a roller 5H is journaled. 'lhis roller rides on the. lower guide or track 38 and the stub shaft 5T extends beyond `t he guides 38 and into the plane of the arm t0 and the series ol pawls lt). titl and 5l above described.

Operation ot the nuwhanisni so t'ar deltltl llo llb

terasse.

scribed takes place in the following manner: When a bale ias been formed and is ready to tie, the operator trips the bail or lever 46 thereby pulling upon one end of lever 43 and causing its other end to push on and release the latch 4l from lug 42 and from its position on heel 40h. This permit-s the arm 40 lt-o drop, bringing its hooked end 40a, in the 1 i When arm 4() is down, stub 57 can pass forwardly under hook 40a, the end of arm 40 being beveled to cause it to ride over the stub, but on its return movement hook 40a will engage the stub and the carriage will be moved backward wit-h the plunger movino with it the pitman 35 and swinging bai'l3l and. with it the wire feeding arms 32 so that the latter pass across the end of the bale carrying the tie wires to the twisting mechanism on the opposite side of the press. y When the plunger reaches the end of its backward stroke, carriage -37 will have traveled from dotted line to vfull line position of Fig. 4

land the edge "i of pawl 50 will engage one edge of lug 52 causing the pawl to swing and its pin-50b to engage the under edge of the cam tail on pawl 49-thro-wing its bill 49-a into engagement with the other edge of lug 52, at the same time locking the pawl series together by engagement of tooth 51a on pawl 5l with step 50c on pawl 50, thereby locking carriage 37 andrelated mechanism to the lug 52 on the press frame. It is to be noted that in this position the cam tail 49b of pawl 49, tail 50L of pawl 50 and the cam track on they horizontal arm of pawl 51. are each in the path of movement of stub-shaft 57. On the next forward stroke of plunger B the` stub 57 will leave the hook 40a and move freely under arm'40 until it Strikes the tail 49b of pawl 49 causing pawl 49 to swing sufliciently to release its bill 49:L from lug 52, the stub then engaging the tail 50a of pawl 50, (left end Fig. 4) which remains locked in position with pawl 5l, and the carriage 37 is thereby moved forwardly until the vertical arm of pawl 51 strikes lug 53 releasing it from pawl 50 which drops and allows the stub-shaft 57 to'ride over the track on the horizontal arm of pawl 5l, at which time it engages an inclined under surface on arm 40 forcing this arm upwardly and lowering its heel 4()b to a position where the end 4lb of the latch 4l snaps back over the heel 40", its. bill 4la at the same time engaging lug 42, thus again lockincr the carriage 37 and mechanism operated tliereby in inoperative position, as indicated by the dotted lines at right end of Fig. 4.

During the above described cycle of operation of thewire-arm swinging mechanism,

' the wire tying or twisting devices on the opagp,

posite side of the baling chamber are also actuated at the roper time and the wires brought across t e bale by the arms 32 are intertwisted with the wire ends held b the twistin mechanism and the twisted en s released t erefrom and bent back into the side of the bale. This is effected `by the mechanism and in the Amanner now described. Openings 59, (Fig. 3) are provided in the side 0f the baling chamber for assage of ends of the wire-arms 32 and adjacent each opening brackets 60 which carry the wire twisting mechanism are mounted in any suitable manner. ach twister includes a main-drive gear 6l connected by an intern1ediate 'gear 61a. These are driven from the gear wheel 62 through intermediatev gear 62a, the gear 62 being formed on one member of a clutchtheJ other member of which carries the gear 63'(Fi0fs. 6 and 7). This` clutch is preferably of the pawl and ratchet type and is controlled by actuation of the wire .feeding mechanism, manner to be later described, it normall being idle,'with gear 63 turning idly wit 'relation'to'gear 62. Gear 63 is in engagement with a reciprocatin rack bar 64 carried by one end of a twin-bar pitman 65 which has its opposite end p-ivotally connected to a pin'tle 66 on a carriage 67 whichis slidably mounted in upper and lower guides 68 on the side of the press and preferably formedwith 'an up# ward extension 67a engaging the upper guide and a forward extension 67b engaging a roller 68a on the lower guide. A brace 69 connects the side of the press with a bearing bracket 7 0 in which one end of the shaft carrying clutch gears '62--63 is mounted. This bracket has an upward extension 70 (Fig. 3) which supports a rollen` 7 Ob under which rack 64 moves, the roller 70h engaging a groove in the back of the rack-bar and serving to guide the bar and keep it in mesh with gear 63.

The carriage 67, like carriage 37 on the opposite side of the press, is 'reciprocated through connection with the plunger in the following manner: A pair of bars 7l, similar to the pair '55` is connected to the opposite side of the plunger B and, in the same manner as on the other side, are joined to a bracket 72 having a laterally extending stub shaft 73 on which a roller 74 is journalled.. This roller rides on lower guide 68 and the stub-shaft extends beyond thev guides and into the plane of the carriage and coupling elements carried thereby. These elementsl comprise a coupling pawl 75 and control pawl 76 both pivoted on carriage 67 in o operating relation. Pawl 75 has a guide slot 75a engaging a stud on the carriage. Its forward edge is of generally arcuate form. At its upper end there is a downwardly extendin notch 75b shaped to receive stub-shaft 73 and below the 4notch there is 'a step 75c in lUO the forward edge for engagement with pawl 76. Pawl 76 is approximately straight and consists of an upper part or head 76n and a lower depending arm 76". ()ne corner of the head 7 6 is shaped to engage the stepJ 75 in pawl 75 toward which'it is pressed y a spring 77 engaged between a lug on ,the carriage and an extension on the head 7 6l (lt`igs. 3 and 5). Assuming the parts just described to be in the position shown in full lines in Fig. 5, the stub 73,011 backward stroke oi the plunger, will engage the notch 75D and cause the pawl 75 to swing until-the stub 73 meets a ledge 67c on carriage 67 at which time the head of pawl 76 will engage step 75c and lock pawl 75 in position. The carriage will then travel with the plunger to the end of its stroke, as in dotted lines Fig. 5, and as pawl 75 is locked, will return with the plunger until arm 76b of pawl 76 strikes a lug 78 fixed to the press. This causes pawl 76 to swing and releases pawl 75 returning it to the position shown in full lines Fig. 5,'

thus releasing the Stub 73. This connection and disconnection of stub 73 with carriage 67 is repeated with each reeiprocation of the plunger and the rack 644 is therefore reciprocated also, but moves idly with gear 63 unless this gear has been connected with gear 62 by tripping the clutch connecting them. This tripping and consequent operation of the wire tying or twisting mechanism to be described, occurs on each actuation of the wire-feeding arms 32 in the following manner:

The lower arml 31h of the bail 31 extends beyond its pivot to form a trip 7 9 -'(Figs. 1

. `and When the bail 31 and wire-arms 32 are caused to swing, as above described,'the trip 79 will swing to dotted line position Fig. l and there corne into engagement with the depending end of a short lever 8O,

(Fig. 3) pivoted at its upper end to the press. Alink 81 is pivotally connected to lever 8O between its ends and a spring 82 positioned between the lever 8O and a lug on link 81 presses the latter downwardly. The free end of link 81 is formed with a notched nose 81n which is positioned between upwardly projecting ears on a trip dog 83, the notch in the nose 81n engaging a lug between the ears. Dog 83 has a trip arm 83L extending in the path of the projecting end of a clutch dog positioned within the clutch and which is thrown out by contact with arm 83, the clutch remaining free until the clutch dog is released by retraction ot link- 81 whichswings trip 83u upwardly, as indicated in dotted lines on Fig. 6.' The clutch do i 83 immediately tends to return to norma osition, under pressure of a spring 8i positioned between the press and dog and rides on a cam track 85 formed on the clutch member adjacent gear 62 until the clutch completes a revolution and the projecting end of the clutch dog is again engaged and the clutch thrown out. 'l he clutch used is of well known t pe and further description of its internalmerhanism is not deemed necessary.

When the clutch is tripped. rack 6l will drive gear 62 on the return or forward stroke of the plunger and through it the train of gears 62-61 by which the wire tying or twisting devices are operated. llach gear 61 drives one of the wire twisters or knotters and as these are duplicates only one will be described. i

The twisting or knotting mechanism conlprises a main interrupted gear wheel 86 (Figs. 8 to 13) fixed to thel same shaft as drive gear 61, a slotted twister pinion 87` and a mutilated pinion 88. 'lhe pinions 87 and 88 are in offset parallel planes and main gear 86 is formed with two sets of gear teeth 86"--86b positioned to engage with the respective pinions. The teeth 86 are formed on the periphery oi' the wheel 86 and extend over approximately two-thirds ot its eircumference, leaving a delay surface 86C. 'leeth 86b are on one end of a flange 86 which is concentric with the peri )hery of the wheel and projects laterally therefrom below the toothed portion of its rim but terminating a little short o1" each end of said toothed portion. Teeth 66b are only six in number and come .into mesh with the tiro opposite sets of five teeth on mutilated pin ion 88 once for each revolution of wheel .86. The teeth on pinion 88 are separated by opposite delay surfaces 88" and in operation each engagement of teeth 86" with pinion- 88 gives it a half revolution. ()n the other hand, each engagement of teeth 86" with pinion 87 imparts three revolutions thereto, following which pinion 87 is idle for the remainder of the revolution oi wheel 86 owing to passage of delay surface 86", at which time pinion 87 is locked against rotav tion by engagement ot' its arcuate locking face 87n with'a. track 86' on the delay Isurface. The outer end of pinion 88 is journaled in bracket 60 (Fig. 8) flush with the face of the bracket and an etwentrie pintle 88b is lixed thereto on which is journaled a link 89 pivotally connected to one eml ol' the wire cutting and grasping lever 06. 'lhis lever is pivoted to the bracket at Sli and its free end is positioned'` between upper and lower graspingdies 92, preferably lformed with wire nieking edges 92 and secured ou knife plates 93. The dies and plates are mounted between lugs 94 on bracket 66 by transverse pins or screws. The openingl through the dies and plates for screws 95 are made slightly larger than these screws. and the lugs 94 carry set-screws 96 which serve to give dies 92 the slight degree et ad- .justinent required. The tree end of lever is bitureated as at 90 for reception oi the tie-wire, land a laterally spaced rigid branch 90b of thev lever has its end opposite the bifurcation and formed with an en larged wire-guiding head 90. The bifurcated end of lever 90 travels across and against the edges of the knife plates having a shearing action therewith. j Pivoted within the bracket 60 at 9'7 is a stripper lever 98 which has a vertical arm 98u positioned' to swing across the axis of twister pinion 87 and a shorter laterally extending arm 98"' provided with a lug lying in the path `of`a'trip 86e on gear 86.

Pivot'ed to the bracket at 99 to the rear of lever 98 is a tucker lever 100. This lever swings upwardly and rearwardly in a plane parallel to that of lever 98 and close thereto and its extreme end also crosses the axis of twister pinion 187 "Intermediate its ends it has a laterally extending arm 10()a which `has a lug at its outer end positioned for engagement by the Iiange 86d. It also has a lateral lug at 100b which is in position to be engaged by a ledge 98c (Figs. 12 and 19) on lever 98 to act 'jas a stop for excessive outward swing of this lever` while a second lug 100c engages a'seeond ledge 98d on lever l98 and acts as a stop to excessive outward swing of lever 100.

When `prepared for operation the wirearms 32 each have a strand of wire threaded through. the guides 32", the eye 32c (Figs. 14 and 16) and around the pulley 32e extending from thereinto the baling chamber where it passes down one side of the bale,

across itsend and up its other side to atwister where each wire end is being held by one of the grasping levers and dies in the manner shown lin Fig. 10, the wires having been pushed back as the bale was' formed.

Operation of the bale binding and wire tying mechanism above described takes place when the operator trips the lever 46 as a bale is completed, this causes engagement of arm 40 on carriage 37 with'stub-shaft 57 in the manner valready described with coni sequent swingingv of the wire-carrying arms across the baling chamber to the position shown in dotted lines-- Fig. 1. Just as the arms 32 reach thisposition, the trip 79 engages the clutch tripping mechanism 80' 81-83 and the clutch connects gears 62-63 for joint revolution. 64 is drawn back to the position shown .in Figs. 1 and 3. Plunger B` then begins its return stroke carrying carriage 67 and rack 64 with it by reason of the coupling mechanism 7 5-76 above described. During the iirst part of the return stroke of the plunger B carriage 37 remains still and the wire arms in their swung position, owing to the fact that stub-shaft 57 travels idly .from its position in the hooked end 4()a (Fig. 4)` until it :comes in contact with pawl 5O At this time rack.

(dotted line position left end Fig. 4). During this interval rack 64 is driving gear 63 which, being locked to gear 62 by a one turn clutch, imparts one revolution to gear 62 and then releases. This one revolution is transmitted -to the drive gears 61 and main gear 86 of each twister and tying or intertwisting of each binding wire takes place. 4

When the tying action starts the twister parts are inthe positions shown in Figs. 8, 9 and 10 and one wire end is held in the twister as seen in Fig. 10. Just before actuation of the twister takes place, the wirearms'32 have each brought a strand of wire across the end of the bale and in proximity to the slot in twister pinion 87 as will be understood from. the dotted line position of the arm 32 in Fig. l and the full line position of the wire in Fig. 14. Operation of the twister then takes place, the first result of rotation of gear 86 in the direction of the arrow Fig. 9, being engagement of fla-nge 86d with the lug on arm .100a of the tucker lever 100.. This raises lever 100 to the position seen in Fig. 13 causing lit to engage and tuck the wire carried by arm A32 into the vslot in the twister pinion and across the forked endof grasping and cutting lever 90, stripper-lever 98 being held back by the wire-retained in the twister. As this takes place, pinion 87 is engaged by teeth 86a by which it is given three revolutions while the tucker 98 remains locked in position by the flange 86d. Just as pinion 87 is completing its third revolution, stub-axle 57 again engages carriage 37 and the wire-arms begin to withdraw the wire causing it to loop vover the guideehead v9()c on leverI 90b the sloping point of which guides thewithdrawing loop so that the wire passes around one branch of the fork in the end oflever v90 with the return strand in the.bifurcation. At the same time teeth 86b engage one of the sets of teeth on pinion 88 giving it a half revolution andcausing the bifurcated end of lever 90 to swing from one clamping die to the other. 1n doing so it releases the old wire and brings the strand of the new wire that' has just beentied to the old one, against the edge of the opposite cutter 'blade just as the severed end is grasped between the opposite die and lever.

Fig. 10, where the dotted lines indicate the position of the released old wire andthe full lines show the newly grasped end of the new wire, will help to illustrate the 0peration. Just as the cutting and grasping of the new wire is completed, the tucker arm 98 is released from the flange 86d and the arm drops by gravity to the position in Fig. 12 after which trip-lug 86e strikes'the lug on arm 9 8b of the stripper lever 98 and swings the leveroutwardly across the axis of the pinion 87 thus stripping the twisted to reciprocate across the baling cha-m wire-ends from the twisting slot of the piuion and torcingthem into the path of movement o'lf an ,arm 32.. During this time arms 32 are continuing to withdraw, paying' out the new wires across the baling chamber as they move, but just as the protruding ends of. the arms are withdrawing into the baling chamber the pocket 32 (Fig. 15) engages the twisted ends of the wires which have just been 'forced out by the stripper lever (dotted lines Fig. 14) and bends them back into the baling chamber whercthe plunger forces the tied ends into the side of the bale.

The positive ejection ol' the intel-twisted wires from the slot oi the twister pinion, and their positive withdrawal into the baling chamber are regarded as important features of my device assuring ellicient operation of the tying mechanism.
